A company makes steel rods shaped like cylinders. Each rod has a diameter of 6 centimeters and a height of 40 centimeters. If the company used 48,607.2 cm^3 of steel, how many rods did it make?

Answer 1

Find the volume of one rod, then divide the total volume of steel used by the volume of one rod. The volume of one rod is

V = (πd²/4)h

d = 6 cm

h = 40 cm

Plug in the numbers and get V in cm³, then divide the given total volume of 48,607.2 cm³ by V. If the result is not an integer, then round down.
